Blood Selenium

Selenium, an essential mineral and antioxidant, is especially potent when it is paired with vitamin E. Antioxidants are elements that protect your body’s cells from the dangers and damage of free radicals. Selenium also assists in thyroid function and may help with lowering LDL, or "bad" cholesterol. Low selenium levels are associated with heart failure, rheumatoid arthritis and certain kinds of cancer.

Used for diseases of the heart and blood vessels, including stroke and "hardening of the arteries". Can also be used for preventing various cancers including cancer of the prostate, stomach, lung and skin.
